Chelsea midfielder Nemanja Matic has admitted that he has improved a lot as a player and is happy with his form after re-signing for the club in January.

Matic was sold by Chelsea to Benfica in 2011, but was bought back just three years later for a much higher price, and he has become a regular starter under Jose Mourinho.

The Serbian believes that the time away has been crucial for his development and told Sky Sports News: "When I first came to Chelsea, I was very young and there were big players in my position, so it was difficult for me to play.

"Now I'm 26 and it is different. I have more experience and have improved a lot. I came here to show that I can play in the Premier League and for Chelsea. I'm happy at the moment."

Matic has played 38 times since his return to the club for a fee in the region of £24m.
